The following footprints are of my CW signals on 2021-March-14 at about 04:00 to 04:20 UTC.

Location: EM89ad – Ohio
Antenna: OCD (Off-center Dipole)

Description of Antenna:

This is an off-center dipole, with the two legs running East-East-South (approximately 125 degrees of North), and West-West-North (about 306 degrees on the compass). The westward wire (leg) is approximately 107 feet in length, while the eastward leg is about 95 feet in length.

These legs (an off-center-fed dipole) is directly connected to about 90 feet of 450-ohm ladder line, which is hanging directly below, vertically, the feed point. The feed point is 50 feet above the ground.

The ladder line terminates (at the 12-feet-above-ground point) to a 4:1 current balun. This current balun then connects to a 100-foot LMR 50-ohm coax, which is running into the radio shack. It is connected via an antenna switch to my Icom IC-7610 transceiver. I am transmitting a 100-watt CW signal using an Icom IC-7610, in the following format:

TEST TEST TEST DE NW7US NW7US NW7US

The Reverse Beacon Network reports any spotting of this test transmission. The beta mapping interface, at http://beta.reversebeacon.net/main.php, then maps the resulting spots. To learn more about the RBN, visit http://beta.reversebeacon.net/index.php, or, http://reversebeacon.net/index.php.

I show the 20-, 30-, 40-, 60-, 80-, and 160-Meter band footprints.

I’ve been capturing these CW transmission spots, at different times of the day, today. I’ll get data from several days, at regular intervals, and create a overview of how the antenna appears to be working during this month and under these propagation conditions.

For those in the UK worried about the new pending Ofcom ICNIRP EMF rules.

I have found an excellent EMF calculator program from the late VK3UM, infact I would say it is the best I have come across yet.

Well worth a download and a play with:

Welcome to the 399th episode of Linux in the Ham Shack. In this episode, the hosts sit down with 75% of the creators and developers of OpenRTX: Niccolo, IU2KIN, Federico, IU2NUO and Sylvano, IU2KWO. We discuss the origins of the OpenRTX project, what it is, what it does and how anyone can participate in its development and use. We also touch on audio codecs, the Open Source philosophy, open hardware, engineering skulduggery and much more. We hope you enjoy this informative, in-depth look at OpenRTX. Have a great week.

While I did not originate the idea, I have been promoting the use of 146.58 MHz as the North America Adventure Frequency.  (Rex/KE6MT and George/Kj6VU came up with the idea.) My previous blog post explained the thinking behind it, along with my own personal biases, I’m sure.

When presented with the idea of The Other Simplex Frequency, I generally get three types of reactions:

1. Great idea! These people generally live or operate in locations where the 2m FM calling frequency (146.52 MHz) can get kind of busy, so they see that having an alternate frequency that everyone knows about has value. They may or may not still call on .52 but having another designated frequency is a plus.

2. It will never get used in my area This reaction comes from locations where people tend to congregate on 146.52 MHz and will probably not monitor any other frequency. The SOTA activators say stuff like “I’ll never contact anyone on 146.58 MHz so I’ll have to just use keep using 146.52.” This is not a problem, do whatever makes sense.  The North America Adventure Frequency will probably not get used everywhere and that is just fine.

3. What, people actually talk on 2m FM simplex? These folks are just plain missing out. I don’t know how to help them.
